Group friends so that I can keep track of the total amount received for an activity
I think it would be great if I could have multiple groups so that I knew in aggregate what each owed me. Here is my justification: I live with roommates who I split utilities and food with. I also have a house in Tahoe that I share with a separate group of people. I would like to keep the two groups separate because the Tahoe bills are large and we also have to keep tighter track of expenses (everyone pays for everything upfront) so we don't run out of money.
You can actually do this already! From the account settings screen, click “Create a group” under “Advanced features” – it’ll let you create a separate group where you can keep track of shared expenses with a set group of people. You can have as many groups as you’d like, for houses, group trips, and more.
